Laser Machine World for Laser Technology and Laser Products

In the wave of rapid development of science and technology, laser technology has become the core driving force of advanced manufacturing industry, profoundly reshaping the production pattern of various industries. Among them, high-speed laser cladding technology has become the key technology in the field of material surface modification and repair by virtue of its significant advantages, and has attracted much attention. In this scientific and technological competition, ZKZM  has stood out from the crowd by virtue of its profound scientific research background and unremitting technological attack, and has become the backbone of leading the technological development of the laser additive manufacturing industry. High-speed laser cladding technology uses a high-energy density laser beam as the heat source to accurately clad special metal alloy powder on the surface of the metal substrate. Under the action of laser energy, the powder is rapidly melted and solidified, forming a metallu...

Laser cleaning is a technology that utilizes a high energy density laser beam to interact with the surface of a material, causing dirt or coatings, etc., to be stripped or decomposed from the surface of the substrate, thus realizing the purpose of cleaning. The laser cleaning process involves a variety of physical mechanisms, such as thermal ablation, stress vibration, thermal expansion, evaporation, phase explosion, evaporation pressure, and plasma impact, etc., which work together to promote the separation of the cleaning object and the substrate to achieve the effect of cleaning.   According to the different cleaning media, laser cleaning can be divided into laser dry cleaning, wet laser cleaning, and laser shock wave cleaning. Laser dry cleaning Laser dry cleaning is currently the most widely used laser cleaning method, the use of laser beams directly irradiates the substrate surface so that the substrate produces thermal expansion to overcome the van der Waals force, to remove...

The roller is an important piece of equipment in the process of a new energy lithium battery. Through the roll pressure, the battery material will be compacted to obtain the prototype of the pole piece.   Roll surface cleaning is very important to ensure production yield!   The traditional way of cleaning rolls, using manual wiping rolls, there are many disadvantages. The use of lasers to complete the rolls of high-quality cleaning is imperative.   In the new energy lithium battery manufacturing process, pressing the battery electrode roller is one of the key steps.   Through roller pressing, the active material on the pole piece (usually powdered positive and negative materials) is compacted to obtain the desired shape and thickness of the pole piece, and keep the surface smooth and flat. The compaction density and thickness of the pole piece, as well as the bonding strength of the active material to the collector foil, have a direct and important impact on the phys...

Photovoltaic power generation is based on the principle of photovoltaic effect and utilizes solar cells to convert sunlight energy directly into electricity. Chalcogenide material is a semiconductor material with a special crystal structure, which is widely used in solar cells. In the preparation process of chalcogenide solar cells, edge clearing is an important step, which helps to remove the excess chalcogenide material at the edge of the cell and avoid the influence of the edge effect on the cell performance. By precisely controlling the edge-clearing process, the structure of the cell can be optimized and the non-radiative composite can be reduced, thus improving the photoelectric conversion efficiency and long-term stability of the cell. In addition, edge clearing helps to improve the appearance quality and overall performance of the cell, making it more reliable and efficient in practical applications. This article mainly provides solutions for the application of Raycus 's fl...

In today's rapidly changing laser technology, solid-state lasers and fiber lasers as the two mainstream laser products, each in industrial production, scientific research, military applications and other areas to show the unique charm and advantages. First, the technical principle and performance differences 1.  Gain medium   Fiber laser (Fiber Laser) is used as a rare earth element doped glass fiber gain medium. Under the action of pump light, high power density is formed in the fiber, resulting in the reversal of the number of particles in the laser energy level, and generate laser oscillations through the positive feedback loop of the resonant cavity. Fiber lasers are compact, do not require complex cooling systems, and the flexibility of the fiber makes it more advantageous in multi-dimensional spatial processing applications.   At the heart of a fiber laser is the optical fiber, a flexible, hair-thin glass or plastic filament known for its ability to direct light ove...
